IM PROVEM ENT IN PLOWS.

To all whom 'it may concern Be it known that I, BENJ. F. AVERY, of the city of Louisville, in the county of Jei'erson and State of Kentucky, have invented a new and Improved Look or Joint Connecting the Mold-Board and Landside of a Plow, also a new method of attaching the mold-board handle to the mold-board; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon.

In my description of my look the plow consists of three pieces of cast-iron-viz., the moldboard, the landside, and the share or point. That part of the mold-board which is covered by the front end of the landside and parallel with it is called the shortlandside.77 Itis represented in Figure l by the red lines, and is a part of and cast solid to the mold-board. It is recessed or sunk below the general surface of the landside part of the plow the thickness of the landside, so that when the landside rests in its place upon it that side of the plow presents an even unbroken surface.

In the short landside are cast two openings. One, Fig. 1, is a Q-shaped hole near its top, marked g. The other is rectangular near its center. Its lower or bottom edge is cut off, throwing the shoulder f, Fig. l, in front of the openings.

Fig. 3 is a drawing of the inside of the landside, having` its Q shaped projection to t into the corresponding opening in the short landside, its strong hook n turning backward toward the heel of the landside, and intended to pass through the right-angled opening in the short landside, and to grasp snugly the heavy bar c, which forms the back part of the saine, the inner 0r under side ot' which bar is made to correspond in form to the curve of the hook a. The iiange h in Fig. 3 has its shoulder j' to iit into the bottom part of the short landside, which has been cut away for that purpose, as shown by ,Fig.1. Thelandside,wheniu place, covers entirely the short landside. This constitutes my lock or joint.

The mold-board, with this lock and these lugs, can be molded safely and rapidly in a ouepart ask. The lock never gets loose by using the plow.

I claim- 1. The lock-joint for holding the laudside to the short landside and mold-board, the same consisting, mainly, of Q-shaped projection g, hook n, and iange h and their counterparts in the short landside.

2. The ears or lugs d d, cast on the inside of' the mold-board for the purpose ot' fastening the mold-board handle.
